Specification of Letters Patent.

Patented Dec. 29, 1908.

To all whom it may concern:

Be it known that I, JESSE G. VINCENT, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Im rovements in Addin -Machines, of which the following is a speci cation.

In adding and listing machines of that type in which a plurality of rows of amount keys are employed and a corresponding number of registering wheels .together constituting the accumulator, and a corresponding number of type carriers, it is customary to provide for so-called splitting of the machine, which means interrupting the cooperation between the impression-making devices whereby automatic printing of ciphers is accomplished. Thus two or more columns of imprints can be run in the same series of operations of the machine, one column representing for example dates and the other amounts opposite those dates. Or the one column may represent} measures as for instance car loads while the other represents amounts op osite such numbers. In the latter case t e totals of both columns will ordinarily be desired whereas when the first column represents dates no total need appear as a footing of such column. As these machines are usually constructed, however, the total of the date numbers would be accumulated upon the wheels corresponding with the columns of keys set apart for the date printing. The ca acity of the balance of the accumulator or running up a total of amounts is under such circumstances necessarily limited. In other words a total exceeding the capacity of those wheels would not be taken care of by the wheel or wheels to the left associated with the column or columns of keys used for date printing urposes because that wheel or those whee s would contain the total of the date numbers. As a total of date numbers is uselessyaddition might just as well be dispensed with on the wheels corresponding to the rows of keys I used for dates, and those wheels reserved for extension of the total being accumulated on the balance of the wheels.

The object of the present invention is to provide improved means for accom lishing this extending of the total whereby w n the machine is operated under a split adjustment for the printing of dates or other numbers not to be accumulated, the total of the amounts accumulated as a result of depression of keys in the balance of the rows and operations of the machine with such keys depressed as well as keys in the row or rows devoted to dates, may exceed the capacity of the wheels associated with the amount rows of keys, to the full capacity of the machine when operating at normal or without a split. It follows that two columns of imprints having been run ofi, one representing dates and the other amounts, a total of the latter can be printed, which total may run to the left below the column of dates, thus tended total notwithstanding the listing has been done with a s lit and consequent elimination of ci hers etween the columns, all as indicated y the above example of worlaand this too, without requiring any readjustment as by restoring the machine to the 1 normal unsplit condition.

The accompanying drawings which form part of this s ecification illustrate the invention as em odied in an adding and listing machine of the well-known Burroughs type as exemplified in William S Burroughs patents 504,903 and 505,078, issued September 12, 1893, but it is to be understood that the invention is not necessarily limited to employment in just this particular construction of adding and listing machines.

Of. said drawings Figure 1- represents a machine of the Burroughs type in left-side elevation with the improvements of the present invention applied thereto and some parts omitted which do not .require illustration or description in order to make clear the application of the present invention to the Burroughs machine.

the drawings the parts are represented as at normal under an adjustment which provides for the use of the machine as an ordinary Burroughs machine, that is without a split; Fig. 2 is a somewhat similar left-sideelevation not, however, illustrating so many parts as are illustrated in Fig. 1 and moreover showing the condition when the machine is adjusted to split though not for the extended total Fig. 3 is a fragmentary top plan view illustrating the manipulating device by which the ditferent adjustments are obtained; Fig. 4 is a view similarto Figs. 1 and 2, representing the condition'when the adjustment for the extended total exists and the total key has been depressed pre-.

parat-ory to printing the total; Fig. 5 is likewise a left-side elevation illustrating some of the same parts which appear in Figs. 1, 2 and 4 but representing a changed relation of these parts to-wit that which exists in an itemizing operation when the operating handle is about to complete its return movement Fig. 6 is a sectional plan view taken substantially on the line 6-6 of Fig. 2; Fig. 7 is a left-side elevation on a somewhat enlarged scale as compared with Figs. 1, 2, 4 and 5 and confined to the front ortion'pf the machine for the purpose of illustrating more particularly a peculiarity in thetransfer or carrying devices due to the employment of the extended total means;

10 a sectional elevation on line 10-10 of Fig. 8 looking in the direction of the arrows.

Before proceeding to describe the special devices employed for carrying out the present invention, some of the usual parts of a Burroughs adding machine will be pointed out. Amount keys 291 arranged in several rows on the keyboard operate as usual when depressed to set stops guided by slots in the upright plates 210 at the front of the mac ine and the depression of these keys also trips. the usual latches 415 through the meditm ofsliding strips 214, said latches releasing the racks 610. The latter are as In this figure of 1 The rear ends of the levers 0 plates 618 to be driven against the roller platen 17 by hammers 715 inally restrain said drivers and 718 the usual pawls which trip said latches, the heels of said awls cooperating as usual with inv cline shoulders on the levers 611 so as to be disabled unless the latter move past the zero position. However, the latches 717 trip each other from left to right as usual for the filling in of ciphers through the medium of the-usual overla ping tails d and a coupling device A, such or example as illustrated in the Go'och Patent No. 825,205, dated July 3, 1906. The latch to the left of this coup ing device has no overlapping tail (see Fig. 6) but this latch and the next one to the right are notched for the engagement of pins or studs on the coupler and the latter is mounted to slide upon a shaft. 706 so'tha'tit can constitute a connecting link between these latches serving the purpose of the overlapping tail. The disengagement of this coupling device from the latches obviously interrupts the t-ri ping of latches from left to right and thus t esplit can be established. A sprin A fastened to the coupler forward of the shaft 706 normally enforces the engagement between the coupler and the latches. A bail B is pivotally mounted between the side plates 710 and 710 of that portion of the framework of the machine which su ports the impression devices, and

this bail hes over the front end of the coupler so that when depressed it may rock the latter and eiiect the split. The bail is drawn downwardly by a spring B which is superior to the spring A but the bail is normally upheld so as to prevent said spring from actin A vertical slide bar C is formed with a hoo c at its lower end which engages under a pin 6 on the. left-hand side of the bail and through this means the latter is normally upheld as shown in Fig. 1, the slide bar being drawn up by a spring C which is su erior to the spring B. The bar 0 is suitably guided through slot-andin connection with the side plate 710* an by running through a slot in a bridge-piece 0 below the upper part of the keyboard.

All of the parts thus far specified are s'ubboard plate 212. there is arranged a slide strip C extending from front to rear, its rear end being upturned and confined in a slot of said keyboard plate 212 while its front end has fastened to it an upright post 0 occupy- A ing slots in thetwo keyboard plates 212 and '213 and a slot in an index plate a secured to.

. below the amount keys. The posts is sur- 'tion of the strip 0 to-wit the ste ciphers being omitted mounted by a knob b? carrying a pointer to travel along the inscri tions on the index plate 0 said inscriptions eing arranged in a row from front to rear and reading Normal, Split and Date (see rig. 3). By sliding the knob C back and forth the strip (3 is slid back and forth. The rear portion of the latter is given an irregular shape form ing steps 0 and c the strip 006 crates with a small roller 0 in the upperen of the vertical bar C. When the strip (1 is in its u most position this roller isln contact with t e stri jl; st beyond the saidirre 'lar portion thereo as illt strated in lig. 1 w ere the vertical bar 0 is'in its uppermost position holding the bail B away from the coupler A. When the knob C is slid from a position indicating normal to a position indicating .s lit, which would bring it to its middle position, the lower one of the two steps formed by the irregular p101- esignated 0 will be forced above the ro ler c and depress the vertical bar C'as ilh strated in lig. 2, thus lowering that bar and permitting the bail B to be drawn down by its spring B and the coupler A thus displaced. Under the last-mentloned adji stment two separate columns of im rints will be made, between them, and the numbers or amounts will be separately accumtlated. The 0 eration of the machine withthe .usual total ey 265 depressed will then result in the printing of the two totals, one as a footing for one co umn and the other as a footing for the other column.

All of the results above described have been attained in prior machines though some of the devices mentioned for producingthe results vary from those heretofore used as already specified. In prior machines it has also been possible to reiventtheprinting of a total at the foot of th and this has been accomplished by an adjustment effected by movement of some such device as the knob C to an extreme position.

In the present instance such movement of the kno C 'i. e. its movement to the upper end of the slot in the index plate 0 bringing its ointer opposite the inscription Date, wil result not only in doing away withthe rinting of the total of the numbers in the eft-hand column, but will also provide for extending the total of the amounts in the right-hand column.

It has been before stated that the racks 610 have the usual slot-and-pin connection with the levers 611. These racks are as usual spring-drawn in upward direction for the purpose of carrying as in the ordinary Burroughs machine and they are normally restrained from movement under the impulse of the springs by the usual transfer This irregular portion of e left-hand column pawls 413. The racks coo erate severally with pinions 9'16 and theatter have the. usual transfer projections for, tripping the v awls 413. In the present instance, however, the inions do not all remain at all times 'axia y ahned as 111' previous machines.

when the knob ismoved to the latter.- osition the two pinions' and the number'w eels carried by them, which belong to the two left-hand rows of keys 'i. e. the rows to the left of the s lit, may remain out of, engagement with t e racks 610 while the remaining pinions move into engagement with their racks. Thus the racks to the left-of the" split may return to normal without afle'cti-ng t eir dpinion's and the only movement-imparte t0 the pinions will be that ,which takes place by reason of the over-running of the 'inions to the right of the split. Thus it will e obvious that'a total to the right of the split can be extended to the left of the split.

All of the pinions 916 are mounted 1n a rocking frame of the usual type, the left-- handside late of which a pears in Figs. 1, 2-and 4 of t e drawings designated 910*, and

the'rocking of this frame about the pivotshaft 900 isdone in the usual way. Thus the pitman 914 normally embraces. wlth its notched upper branch a stud 958 on the side plate 910 above the pivot shaft 900 and said pitman is moved back and forth by the rocking is accomplished in the usual way by the action of a wipe-plate or pawl 821 upon studs 961 and 961 on the three-armed lever,

They do so remain as long as the knob C is not moved to the date position but-- 'rocklng of the three-armed lever 913. This said wipe-pawl being carried by an oscillat:

ing arm 813.- The lower branch of the pitman is as usual hook-shaped for engagement with a stud 958' on the plate 910' below the pivot shaft 900. Depression of the total key 265 lowers the pitman through the medium of a link 911 so as to engage the pitman in the usual way with said stud 958".

Now the two left-hand inions and their number wheels are carried 1n an inner frame movable about the shaft 900 independently of the main frame of which the side plate 910" is a part. This main frame as usual comprisesintermediate plates 910 besides a right-hand plate similar to the left-hand plate 910*, and also tie strips 910., and a tie rod 910. The wheels and inions to the right of the split are separate y mounted as usual between pairs of plates 910. The tiestrips 910* do not extend as usual to the left-hand side of the main frame but terminate as shown in Fig. 8 atthe plate 910 which supports the left-hand journal of the wheel and pinion belon ing tothe third row of keys from the left. Plates 920 somewhat similar to the usual plates 910 are used-to the left of the split but are slotted at ewhere they-embrace the tie-rod 910". These special plates 920 of which there are four make up the'inner frame before mentioned, together with short tie-rods 920 which connect the plates. The frame thus com osed su ports in its upper portion the'two eft-han pinions and numer wheelsv independently mounted" for rotation inmuch the same way as the balance of the pinions and wheels. It will be noted that this inner frame may rock on the shaft 900 independently of the main frame an eX- tent determined by the length of the slots 6. This is suflicient to disengage the two lefthand pinions from. their racks while the remainingpinions are engaged with their racks. The left-hand side late 920 'of the inner frame has a forwardly and downwardly eX- tending arm 920 which carries ascrew stud f at its extremity. On this stud are loosely mounted a air of latches F and F, each separately rawn downward b springs f and f tending to engage the late ies over the rear of the stud 958 which is elongated for the purpose. When either of these latches is engaged with that stud the inner frame is locked to the main frame and will operate as though a part of it. The lefthand latch F. is normally disengaged from said stud by reason of the fact that the upper edge of the pitman 914 just in rear of its notch abuts the under-edge of the latch as shown in Figs. 1 and 2, but the right-hand latch F is normally engaged with the stud and remains so as long as the knob O is not moved to thefdates adjustment.

The strip C which is slid back and forth by the sald knob has at an intermediate point a cam-rise When the strip is moved eyond the s lit adjustment, that is to say when the kno is moved to the date position, this cam-rise of the stri acts' upon a rollerf carried in therear'en of alarm F secured to a rock-shaft 200 and extending in rear thereof. The depression of this arm by the rearward movement of the strip, rocks the shaft and elevates an arm F secured to the latter and projecting forwardly. This arm F is connecte by a dep 'ndent link F i with the latch F,',,being hooke under a stud on said latch as shown at y' in Fig. 2. v A ipring F draws downwardly upon the arm 3 permitting the latch F to maintain its engagement with the stud 958 so long as the knob C is not moved to the date osition. With the knob at the date ad ustment and the innerframe unlatched from the regular accumulator frame, in an itemizing operation both frames will be swung forward in the usualway, the tie-rod 910 carrying the inner frame along with the outer frame. However, the inner frame will not be returned with the outer frame, not bein latched thereto and hence the two left-ham racks in rising will have no effect upon the pinions in this inner frame. It will thus be seen that so long as the inner frame is uneoaeso necessary in order tosecure the extended.

total that these two left-hand wheels shall return to mesh with their racks in time to take transfers from the wheels to the right and from one to the other. Therefore, means are rovidedfor rocking the inner frame just as t e handle reaches the end of its return stroke and immediately after the restoring bail 613 has reached its home position. The left-hand plate 920 of the inner frame is extended downward as clearly shown in Fig. 5 and there is jointed to it a link 920 which at its rear end is curved and slotted as shown at g to engage a stud g onthe rocking arm 813. This last-mentioned figure of the draw- 'ings illustrates the relation of parts under a obvious that if the adjacent wheel of the regular set has tripped its transfer pawl the carrying movement will take efiect upon the right-hand one of the two wheels in the inner frame and if that movement imparted to such wheel carries it past the nine osition then it will in turn trip the trans er pawl associated with. it and cause a carryin movement to take. place in the other whee in the inner frame.

As the extended total wheels may be out. of mesh at the time the transfer'p'awl istripped by the adjacent wheel of the regular set, it is necessary to provide means for preventing the transfer or carrying movement of the rack for the right-hand one of the extended total wheels, until that wheel comes into mesh with the rack. Such means are illustrated more clearly in Fig. 7 though they also appear in Fig. 5 and that figure should beconsulted as it shows the opposite adj ustment to that illustrated in Fig. 7. The latter illustrates the normal position and it will be observed that there is swung from the same stud that supports the transfer pawl 413 another pawl 413* having a finger h se arated from its main portion a little more t an the diameter of the usual stud 414 onthe rack which cooperates with the regular transfer a'wl. This fin or it normally stands in rear of that stud as s own in Fig. 7 so that it does not obstruct the same. This auxiliary transfer pawl is drawn forward by a spring i but is normally held rearward by the inner accumulator frame, one of whose plates 920 is formed with a rearwardly and upwardly projecting arm h having a forwardly-turned upper end portion with a laterally projecting flange k standing in front of the lower rounded extremity h of the auxiliary trans: fer pawl as clearly illustrated Fig. 7. When the inner frame rocks forward the auxiliary transfer pawl follows it by reason of the action of the spring '5 and the finger h is then brought to position over the stud 414 as illustrated iILFig. 5. The rocking back of the regular frame of course has no effect upon this auxiliary awl. restrain the rack unti the inner frame rocks back and its inions are enga ed with its racks. Then t e restrained rac is released by the auxiliary pawl and thetransfer may take place. To prevent the inner frame from accidentally returning to mesh with the racks its Wei ht is supplemented by a spring tending to old the frame in its outer position, said spring bein attached to a forwardly projecting arm 0 one of the plates 920 and to a fixture on the lower part of the regular side plate 910. In order to rint the extended total it will be understoo that all the hammer driver latches should be cooperatively related. Of course during the itemizing under the date adjustment" the split is effective. This means of course that the coupler A is raised out f eng geme t h he se ond and third latches counting from the left.

' When an extended total is to be taken this tend coupler should be restored as of course the accumulator wheels to the left of the split come into play. To this end means are provided whereby the depression of the total .key will result in restoring said coupler to operatii e position. To this end the bail B is formed with an an 'ular forward extension 13 which extends un er a roll m on the rear end of a curved lever M whose upwardl ex.-

arm has pivotally connected with it a link embrace a stud m upon a rearward rojectipn of the vertical 'bar 0. The link as an upstanding rear portion carrying a stud m A spring m attached to the link M tends to draw the same forward and! therefore elevate the rearwardly-extendin arm of the lever M and prevent it from a ecting the bail B;-

The usual bell crank lever 227 on which the total key is mounted is connected by a link 226 (Fig. 4) with an arm 227 dependi from and secured to a rock-shaft 206, an

the latter has secured to it another depending arm N bent over and doubled back at.- its lower extremity (see Fig. 6) forming afoot 12. adapted to operate upon this stud mi'under certain conditions. It will be noted that the position of the link M is determined by the adjustment of the bar C and the latter is of course determined by the manipulation of the knob C While the knob remains either at normal or at spli adjustment the bar C is not lowered far enough to brin the said stud m in line with the foot 12. (see igs.

It continues to notched latches 717.

(Fig. 2) longitudinally slottedto' depression of the total key. However, when the knob C is moved to the date position the step c of the irregular portion of the strip C l y an further depresses the latter. This brings the stud m in line with the foot n. Conseriuently when the total key is depressed as 1 1 lustrated in Fig. 4 said foot acts on the .stud and draws the link M rearwardlf rocking the lever M and raising the bail by pressure of the roll m u on the forward extension of said bail. T 's ermits the coupler A to become engage with the Hence the tripping from right to left throughout the entire se' ries of latches takes place.,

Of course it will be understood'that in or der to obtain the extended total all the inions must remain in engagement with t eir racks during the forward stroke of the 0 erating handle. Now the spring as wel as theweight of the inner accumulator frame and its two pinionsand wheels will tend to disengage these pinions from their racks as the arm 813 starts rearward relieving the link 920 of the restraint imposed upon it the stud g. It is in this connection that the the pitman 914 so as not to en age the stud 958 (Figs. 1 and 2). When t e 1pitman is lowered by depression of the tota key said latch F drops behind the said stud 958 as shown in Fig. 4and thus prevents the dis.- engagement of the two pinions from their racks. All of the accumulating pinions move out of mesh with their racks at the beginning of the rear or return stroke of the operatinghandle as usual the taking ofa rand total on a regular Burrou hs machine.

f course at the conclusion of t e operation the itman 914'rises to its'normal position and ifts the latch F but the inner accumu-.

lator frame has meantime been rocked through the medium of the link 920 so as to engage-the two extended total pinions with their racks at the same time that the balance of the pinions are returned to engagement with the racks through the usual means. Depression of the sub-total key. 265 produces the same result of engaging the latch F with the stud 958, inasmuch as said keg also operates to depress the itman thoug not to the same extent as t e key 265 yet sufficiently to permit the latch F to fully de-v scend. With the inner accumulator frame and the outer or main accumulator frame thus locked together the'extended total pin-- ions as well as the balance of the pinions will remain in engagement with the racks throughout the operation when a s'ub-total is.

taken, the stud 9 having arrived at the forward and of the slot in the link 920 by the 70 rides over the' roll 0 on the bar C a time the latch F is lifted as a result of rel course if further'itemiz'ing was to be done lease of the sub-total key and consequent rise of the pitman 914. The sub-total key like the total key surmounts a bell crank le- V61 227 and the latter is connected to a link 227 extending over a stud 0 on the lever 227 and formed with a lug 0" to act against said stud so that'in depression of the sub-total key the total key will also be depressed. 10 Said link 227 extends under a stud p on the link-911 and has a high portion p just beyond a notch in its upper edge, so that when the sub-total key is depressed'the rearward movement of the link 227 will bring this high portion under said studp to hunt the downward movement of the link 911 and consequently of the pitman, thus preventing the engagement between the latter and the stud 958 which in a grand totaling operation efiects the disengagement of the from the racks before the latter start to-ascend."

The return of the accumulator wheels to mesh with the racks at the conclusion of a grand totaling operation is effected through the usual means employed ina Burroughs machine, the same comprising a rearwardly projecting arm 919 secured to the rock shaft 900 near its right-hand end and having a cam edge 'actedupon by a roller 311 on the gull stroke sector 311, all as illustrated in 1g. 1.

The usual form of locking means is employed to prevent turning of the pinions when disengaged from their racks, said locking means comprising a frame journaled on the shaft 900 and composed of side plates 926, intermediate plates 926 with locking noses, and cross rods 926 Said frame co- 0 crates with the usual locking lever such as il ustrated in Burroughs Patent 504,963. it will be understood that whenever the accumulator wheels to the right of the split move out of mesh with their racks the wheels to the left of the split must necessarily be moved ends of the slots 6. Consequently the ex- '5 0- tended total pinlons are locked against turn-.

ing just the same as though they were mounted in the ordinary Way and not in a,

su port capable of independent movement.

lit will be seen that the above-described construction is well adapted to produce the results referred to at the outset of this specification and it is particularly to be noted that provision is made for the filling in of ci hers m an extended total where ciphers wou d be omitted in itemizing operations to be thus totalized. Of course after having printed two columns under the date adjustment I the printing of an extended total with ciphers thus filled in might be accomplished b mov- .65 ing the knob back to normal but'of pinions with the expectation of utilizing the extended total feature, said knob would have to be read usted to the date position. The ab ovedescribed construction provides for the filling in of ciphers in the extended total without requiring any manipulation of the knob C Uonsequently the machine can be operated indefinitely under the date adjustment and as many totals or sub-totals printed as desired without requiring any special manipulation. I

While the above-describ ed construction is wellcal culated to serve the purposes in view yet it is to be understood as susceptible of considerable modification without departing from the spirit and scope of the invention.-
